ALKALINE PULP HAVING LOW AVERAGE DEGREE OF POLYMERIZATION VALUES AND METHOD OF PRODUCING THE SAME |
摘要 |
<p>The present invention provides compositions, useful for making lyocell fiber s, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization (D.P.) and a narro w molecular weight distribution. Further, the present invention provides processes for making compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization and a narrow molecular weight distribution. The present invention also provides lyocell fibers containing a high proportion of hemicellulose.</p> |
